Application filed June 1', 1905. Serial No. 263,222.

' of Jersey City, Hudson county, State of New Jersey, have inventedImprovements in Speed Indicators and Recorders, of which the followingis a specification.

The object of this invention is to an apparatusfor use on vehicles,artlcularly self propelled vehicles, that will produce a permanentrecord of distances traveled and the variousrates of speed of travel ofthe vehicle, a visual indicator of the speed of the vehicle at any andat all times while it is traveling and an audible indication, adapted tobe produced at will, when the vehicle is traveling at a speed in excessof a predetermined speed or a prescribed limit of speed.

This nvention contemplates inclosing all of the operating and indicatingparts or devices in a secured casing to prevent interference ortampering with said devices, and so locating the permanent record oftravel and speedsthat the same will be visible, and open to commoninspection, showing distances run and speeds made by the vehicle for aconsiderable period just preceding the time of inspection, or the timethe motion of the vehicle is arrested.

, This apparatus includes a controller which is suitably connected toand ositively moves with apart of'the vehicle tiat'is always in actionwhen the vehicle is traveling, preferably onev of the wheels of thesame; a feeding device for. moving a permanent record receiver inaccordance with the dlstances trav' ele'd, actuated by or in'conjunctionwith the ,"controller; a marking device, preferably in the form of apuncturing point, set into position to mark the record receiver toindicatedifferent speeds of the vehicle by connecting speeds, as milesper hour, of travel of the vehicle; and a sound producing device adaptedto be put in action, at will, from any part of the vehicle, by means ofa connecting cord or chain attached to its operating lever rovidelocated at the end of the casing of theap aratus, so constructed andarranged tfiat audible indications will be produced only when the,vehicleis traveling at s eeds above a given speed, predetermined, w ichmay be a legally prescribed speed. These and other special features ofconstruction will now be fullyqdescribed by reference had to the accoman in drawin s in which' D 7 7 Figure 1, is a perspective view of themachine, complete. Fig. 2, is an end view with the cover removed,showing the record receiving aper, its puncturing and feeding devices.the line 3, 3, Fig. 2. Fig.'f4, is a transverse section, taken on theline 4, 4,' Fig. 3, and also showing the ,alarm device. Fig. 5, is aplan view, with the top of'the casingremoved. Fig. 6, is a face view ofthe governor or distance and speed indicator controller. Fig. 7, is aperspective view of the record producing device and speedindicatingscale.' Fig. 8, is a detached view of'one of the slotted arms of thespeed indicator controller, and Fig. 9, shows a portion of the recordreceiving paper. I

A l the mechanism is contained in a closed box or casing, consisting ofa base a and an end wall I) included in one piece or casting;

and the other wall, the two sides and the top of the casing is includedone piece or castmg 0. These twov parts are secured together by' screws,as shown-at, Fig. 1.v

and the; end wallof the casing 0 respectively,

ig. 3, is .a vertical section, taken on 'Bearingsd and e are centrallylocated in the end wall I) positively rotating part of the vehicle towhich the machine is attached, as for instance one of the traveling orguiding wheels. In the end wall of the case 0 two recesses are formed,in one of which a roll of record receiving paper it is placed, passingtherefrom between a spring t and side plate or wall j, over a table 70and between a feeding roller l and a pressure roller m, hence it entersthe other recess, after receiving the record marks or punctures. Thetable k has a slot through which .the record marking or puncturingdevice n passes to mark the paper It; and the pressure roller m iscarried by .a flexible arm 0 hinged at its lower end to a lug of thecasing c, in such manner as to be casing above the table 7c, it isprovided with the casing c.

' 1pins 1', one being shown at Fig. 3, which enter oles in the top ofthe casing, and it has an opening in its end which snugly embraces t eboss of the bearing 6, thereby holding the cover firmly on the casin andit'is also formed to straddle the sta ner'that when the padloc t isengaged in said staple the cover g is securely locked on The top of thecover is provided with a glass protected opening a, through which therecord paper h is observ able. A strip of flexible material 2), as indiarubber, may be placed between the casing c and the edge of the cover q,to make the joint between them water-tight. The flexible arm 0 isrovided with a boss or lug w, against WlllCll the side of the cover g,bears to cause the roller m to press on and force the paper h againstthefeed roller Z; and when the cover is removed the roller m is free tomove away from the feed roller Z to permit of the ready adjustment ofthe paper it between the rollers.

A visual speed indicator 0:, adapted to move in unison with thepuncturing device n, as hereafter described, is seen through a glasscovered opening in the top of the casing c. A plug y screwed orotherwise secured to the top of the casing covers an o ening therein,through which the operating evices may be lubricated and the controllingsprings of the governor adjusted. The apparatus is provided with analarm or sound producing device, which may be ut in action at will bythe manipulation of t e lever 2, which may be accomplished from any partof the vehicle bymeans of a connecting cord.

To the shaft f, which is rotated at speeds proportionate to the rates oftravel of the vehicle, is secured the controller, whose function is toovern and regulate the movement of the indicating and recording devices,

and whichmay be of the nature of a centrifugal governor as shown,comprising a bar 1 rigidly attached to the shaft 1, two weights 2, 2carried 'on arms pivoted at 3, 3 to the ends of the bar 1; links 4, 4connected to the arms of the weights 2, 2 at points equidistant fromtheir pivots 3, 3 and springs 5, 5,

attached by one of their ends'to the extensions 6, 6 of the links, andby their other ends, through the medium of adjusting means, as screwsand nuts, to the extensions 7, 7 of said links; the arrangement of theparts of this mechanism being such that the springs 5, 5 oppose thecentrifugal force acting on the weights 2, 2 tending at all times tomove said weights towards the axis of the governor, and being capable ofadj ust ment they may be so set that the weights will move through theirrange of action commensurate with speeds it is desired to indicate bytheapparatus, and that there is a e s in such manperfect balance at alltimes of all the parts. On the shaft f is fitted to slide a sleeve 8provided with arms or lates in which. are formed cam slots 9, 9 t roughwhich extend studs or rollers 10, 10 secured to the ends of the weights2, 2. These slots 9, 9 are so shaped that the sleeve 8 will move inaccordance with the requisite or desired movements of the record markingdevice and'the visual speed indicator, which are suitably connected tothe sleeve, as hereafter described. A portion 11, 11 of the inner endsof each of the slots 9, 9 are preferably straight, or radial indirection, so that the weights 2, 2 will not impartany movement to thesleeve 8 1 until the minimum speed which it is deemed advisable torecord is exceeded.

The permanent record producing device consisting of the uncturing oint'n, is carried at one end of a ever 12, w 'ch is pivotally connected toan arm 13 secured to a shaft 14, fitted to rock in lugs 15, 15 on thebase plate a; and to this shaft 14 is also secured an arm 16 formed withstuds or rollers 17 at its upper end to engage, with a groove 18 in thesleeve 8. The other end of the lever 12 has a pin 19 arranged to work inthe slot 20 formed in an' extension of a lever 21, fitted to rock on astud 22 secured in the wall I). This lever is spring actuated, wherebyit is normally-held in upward position against the stop pin- 23, andwhen in this position the puncturing point n is held beneath and awayfrom the record paper it, in whatever position the lever 12 may be setby the action of the s eed indicator controller on the sleeve 8.swinging armor lever 24 also has its bearing on the stud 22'; it is flatand resilient and is provided with a lug 25 arranged to bear on a cam26, fitted to rotate on the inner boss of the central bearing (Z, and iscontrolled and rotated by the main shaft f, through a simple system ofgearin at a speed very much low that of the s aft, whose speed has to besomewhat high for the governing device to properly perform its function,their ratio of speeds being such that a revolution of the cam willrepresent any selected unit of dis tance, for instance it may makeonerevolution for each mile, or fraction of a mile, run by the vehicle.This speed reducing gear consists of four flat gear wheels 27, 28, 29,and 30 of substantially the same size but having different number ofteeth; the wheel 27 is secured to the cam 26 and meshes into wheel 29,which with wheel 30, to which it is rigidly fastened, revolves on a stud31 proj ecting from the rear of the bar 1, and the wheel 30 meshes intowheel 28, which is rigidly secured on the end of the boss of the bearing(1. Wheels 29 and 30 are counter balanced by a weight32,secured,diametrically thereto, on the bar 1. To the lever 24 formedto catch. over stud 34 pro3ecting from I the lever 21, and is caused tocoact therewith pawl lug 42.

jury to the apparatus shou ment being such that the spring also acts toraise the lever 21 and hold it against the stop 23. The lower end of thelatch 33 has an arm 37 which strikes against an adjustable stop 38 whenthe lever 24 is moved towards the axis of the shaft, and so causes thelatch to releasethelever 21. The lever 24 is thus moved, and the lug 25is held against the cam 26 by a spring 39, one end of which is fastenedto-an arm 40 of a link 41, which is pivoted to the lever 24 by one ofits ends and carries at its other end a pawl lug 42, arranged to engagea ratchet wheel 43, ofthe record paper vfee'di'rng device; the's ring 39so acts on the link 41 that the pawl ug 42 is held'against said ratchetwheel 43, and its other end is' f-astened to a-retaining pawl 44, whichis pivoted at 45 to the wall I) and which looks the ratchet wheel as itis moved by the It will thus be observed that this spring 39 has atriple duty to perform, it holds the lin 41 in pro er positlon for thepawl lug42 operate t e ratchet wheel 43, 1t moveslth action of the cam26, and it controls the retaining pawl 44 of the, ratchet wheel 43 and.snapped towards and suddenly pierce the paper h, but is instantlywithdrawn because as the puncturing occurs the arm 37 of the latch 33contacts with the stop 38 thereby moves its u per end away from the lug34 and allows t e s ring 35 to restore the lever 21 to its normaposition, in which it holds the point n of the lever 1.2 awa from thepaper 71-. This sudden triggerike action of the puncturing is veryadvantageous, it insures clearly defined puncture marks under allconditions of ,use of the apparatus on a moving vehicle. ,The upwardmovement of the paper while being unctured is resisted by the edge 58 ofthe en of theglass covered 0 ening 'u of the case cover When t e vehicleis going ahead t 1e cam rotates in the direction indicated by the arrow,at Fig. 4, and as it is in positive communication with .one of thewheels, or other suitable moving part of the vehicle, it moves at speedscommensurate with those of the vehicle; and to provide for )revention ofinid the vehicle be run backwan s when the lug 25 of the lever 24' is ata low part of the cam 26;.circular inclined grooves 46 are formed in therear side ever 24 in opposition to thev of the cam, into which the lugwill enter, the flexibility of the lever .24- permitting it to bedepressed sufficiently for the lug to pass behind the cam and be snappedover the edge should the backward movement carry the inclined groove ofthe cam over and beyond the lug 25. l

The feed roller Z is carried on the end of the shaft 47, by a screwthread or other suitable attachment, and this shaft has bearings in theend walls of the casing, at the upper part thereof, and the ratchetwheel 43 is secured to it near the end wall I).

The visual indicator, is shown as a series of numbers, between theminimum speed it is desired to indicate and the maximum speed theapparatus is designed to be used under, on a segmental plate x carriedin the end of an arm 48 immediately beneath the top of the casing, the oening through which this indicator is visib e being sufliciently lon fortwo of the numbers to be seen, so that t e s eed of the vehicle maybereadily ascertaine an index mark at the center of the o ening clearlyshowing the rate of. 'travel, t e figures preferably indicating milesper hour. The arm 48 is pivoted at 49 preferably to the upper end ofpost 50 which extends from the base a, it has a lateral extension 51which by a pin andslot connection 52 j oins' the upper end of the arm13, whereby said indicator x is caused to move in unison with therecordmarking device n.

To produce a sound,1at will, that will in form the occupants of thevehicle when the prescribed speed limit is being exceeded, which issupposed, by the illustration, in this case to be 10 miles per hour, asmall hammer 53 carried on the end of a rod extending from the sleeve 8strikes a gong or other sound giving device, shown as a spring-plate orbar 43 rigidly secured by its lower end to the base a, it being soshaped that when in normal osition it is out of range of the revolving1ammer at all speeds of the vehicle,

also out of ran e of said hammer, even 'when pressed forwar to be withinthe circle of motion of the hammer, when the speed is at or below theprescribed limit; the hammer at such times being in a plane outside ofthe edge of the spring bar 54, as shown at Fig. 5. Behind the spring bar54 is a tappet 55 carried by a shaft 56, having bearings in 'a lug onthe base a and in the end wall I), the operating lever z being connectedto the end of this shaft which projects beyond the wall I). Now, by themani ulation of this lever 2, as before described, t 0 spring bar 54 ispressed forward and is struck by the hammer 53, but, only when thesleeve 8 has been moved by the sprin bar 54.

It Wlll e understood that the permanent record of miles traveled andspeeds of the vehicle at determined intervals may be made to meet secial requirements; the strip of paper it wil preferably have 1011itudinal divisions or markings thereon Whic will indicate the rates ofspeed by the punctures made by the point a, and vertical divisions ormarkings to indicate the miles run; and these divisions, as shown atFig. 9, which is an illustrative example of a record strip, may besuitably numbered, the horizontal markings, for instance, by the numbers10, 14, 18,22, 26 and 30, which for ordinary purposes will give -asufliciently close guide for the ascertainment of the actual speeds ofdifferent parts of a run, and the vertical markings may, as forinstance, be numbered to indicate each succeeding run of five miles, asshown by the figures 10, 15, 20, and so forth, throughout the Wholelength of a record strip if desired,

or these mile indicators may be divided into sections of any number ofmiles run. In this example the puncture marks 57 are shown giving speedrecords at every half mile;

this feature, of course, may be varied as required, any number of milesor any fractional parts of a mile run may be indicated by appropriatelyproportioning the speed of the apparatus to that of the vehicle and thecontrolling gears and cam of the apparatus.
